Carbide burrs 1416

Tungsten carbide burr (rotor cutter) DIN 8032/8033 Application recommendations: • Use high turning speeds, if possible. Please observe our turning/cutting speed recommendations. With stationary use or countersunk jobs with 360°-wraps, this burr can be used at speeds below 3000 min -1 as an exception. • Only use with rigid clamping systems/drives; tool beat and rattle leads to premature wear. • The contact surface of the burr to the workpiece should not exceed one third of the circumference during processing. An excessively large wrap angle of > 1/3 leads to uneven milling behaviour. This leads to tooth breakage. -

– 6 mm shaft ∅

• For poor heat conductors such as stainless steel, titanium alloys etc., we recommend a significant reduction in turning speed to avoid damaging the tool. Blue staining to the shank and tool should be avoided. • For heavily lubricating materials it is sensible to use lubricants (grease, petroleum, chalk or other) to prevent the tooth system clogging. Carbide burrs can generally be reground. Re-grinding of small and miniature burrs is not advisable due to economic reasons.
